SamplesAnalogInput
Name:
SamplesAnalogInput01 to SamplesAnalogInput04
If the corresponding SamplesAnalogInput register is equal to 0, then the "AnalogInput01-04" data points will provide
the current input value for the analog input.
If the SamplesAnalogInput register is greater than 0, the characteristic value configured in "AnalogInputConfig01"
for the respective channel is calculated. For this, the number of samples configured in this register will be used
and displayed in the corresponding AnalogInput with the configured scaling.

Value
Description
0 = The samples are set cyclically via the register AnalogInputSamples01 - 04
Bit 15
1 = The samples are configured using the register AnalogInputSamples01 - 04
> 8191
Invalid
8191 to 1
Characteristic value calculation active for the respective channel in the corresponding analog
input
UINT
0
Characteristic value calculation not active for the respective channel in the corresponding analog
input
Table 746: SamplesAnalogInput01-04
If Bit 15 of the SamplesAnalogInput is 1, then the parameter configured in "AnalogInputConfig01" is also calculated.
However, the number of samples set cyclically in the AnalogInputSamples register will be used and displayed in
the corresponding AnalogInput with the configured scaling.
The time between 2 samples depends on MaxFrequencyRaw:
